MPI Melt Pressure’s sensor solutions include an industry-first standard Inconel diaphragm that provides extremely long life with superior abrasion and corrosion protection. Optional tip coatings can also be provided, including TiAIN, TiN, and Hastelloy. The industry-standard mercury fill sensor provides high accuracy and durability. Food/medical grade NaK and oil fills are also available to meet your application requirements. All sensors are backed by a full 3-year warranty covering manufacturing defects.

MPI Melt Pressure’s indicators and alarm units are specially designed for easy operation. They require only a one-page instruction manual, but are still fully field-configurable.

Digital and mechanical melt pressure gauges provide a quick and easy option for local pressure indication. Mechanical gauges require no power or wiring. Digital gauges provide an alarm option and have been designed to provide long life in harsh plastic extrusion environments.
